_D_e_s_c_r_i_p_t_i_o_n:

     Compute points on the ellipsoid boundary, mostly for drawing.

_U_s_a_g_e:

     ## S3 method for class 'ellipsoid':
     predict(object, n.out=201, ...)
     ellipsoidPoints(A, d2, loc, n=201)

_A_r_g_u_m_e_n_t_s:

  object: an object of class 'ellipsoid', typically from
          'ellipsoidhull()'.

 n.out,n: the number of points to create.

A, d2, loc: arguments of the auxilary 'ellipsoidPoints', see below.

     ...: passed to and from methods.

_D_e_t_a_i_l_s:

     Note 'ellipsoidPoints' is the workhorse function of the
     'predict.ellipsoid' method; the class of 'object' is not checked;
     it must solely have valid components 'loc' (length p), the p x p
     matrix 'cov' (corresponding to 'A') and 'd2' for the center, the
     shape (``covariance'') matrix and the squared average radius or
     distance.

_V_a_l_u_e:

     a numeric matrix of dimension 'n.out' times p.

_S_e_e _A_l_s_o:

     'ellipsoidhull', also for examples.
